In Reply to: One side colder than other posted by Sher on September 21, 1997 at 22:37:02:
: What causes the left leg and hand to be ice cold, while the other side is
normal? My dad has parkinson's disease and a recent MRI showed that he had a stroke. Are these
problems related to the body being cold on one side only? Thank you
There are several things that can cause change of body temperature making one extremity or one side of body colder than the rest of body. These include both physiological conditions such as exposing to outside temperature, and pathological such as in certain vascular regulatory conditions. The physiologic ones are not much of a concern, and the body can self adjust back to normal. The pathological ones are related to clinical conditions. In most cases, there is a regulatory problem, meaning the mechanism that regulate the constriction and dilatation of peripheral vessels are not functioning well. Under normal circumstances, the vessels go through a sequence of constriction and dilation to best fit the ambient temperature. When the regulation is lost, the vessels will not dilate, and then the limb become cold. Patients with Parkinson
